Preamble Type
: A preamble is a signal used in wireless environment to synchronize
the transmitting timing including Synchronization and Start frame delimiter. In a "
noisy
"
network environment, the Preamble Type should be set to Long Preamble. The Short
Preamble is intended for applications where minimum overhead and maximum
performance is desired. If in a "noisy" network environment, the performance will be
decreased.
IAPP:
IAPP (Inter Access Point Protocol) is designed for the enforcement of unique
association throughout a ESS (Extended Service Set) and a secure exchange of
station’s security context between current access point (AP) and new AP during
handoff period.
Protection:
Select Enabled or Disabled to execute the security function.
Aggregation:
Select Enabled or Disabled to execute this function.
Short GI:
Select Enabled or Disabled to execute this function.
Client Isolation:
The default setting is “
Disable
”. When enabled, the wireless clients
will not be able to communicate with each other. This feature is useful for public WiFi,
WISP operators, and Hotspot operators.
RF Output Power
: You can adjust the transmit output power of the N.TOP’s radio.
The higher the output power, the more distance N.TOP can deliver. However, it is
advised that you use just enough output power so it will not create excessive
interference for the environment. Also, using too much power at close distance can
create serious performance drop due to signal distortion.
If you are not getting good signal, you can try to increase the output power. However;
if your signal appear to be strong but the performance is low, it is advised to reduce the
output power.
Please make sure not to exceed the legal limit of output power in your country. For
EU, it is limited to 20dBm. For U.S.A., the limit is 23dBm.
Ack timeout
: Acknowledgement Timeout Windows. When a packet is sent out from
one wireless station to the other, it will waits for an Acknowledgement frame from the
remote station. The station will only wait for a certain amount of time, this time is
